In the same way that humans seek individual relationships (partners, family, friends), there is much value to communities and tribal level organization. The Dunbar number has been placed at 150 connections that humans are wired to maintain comfortably. Plus, coming together in larger groups helps us to ensure our communities are healthy, to support each other, and to influence larger spheres.
This organization itself is a community, and is part of other networks and communities that serve these purposes. It is important to think about what communities we are a part of, and how we can contribute.
They may take the form of church communities, intellectual communities, political communities, hobby based communities, and more. All are valuable.
